China Unicom's (CHU) Beijing branch has announced that it will formally provide GPRS international roaming service and roaming service in Hong Kong, Macau and Taiwan to GSM post-pay users.

Hong Kong and Taiwan have become the first two areas where the service is launched. GSM post-pay users who open the international roaming service will be able to use China Unicom's GPRS services in Hong Kong and Taiwan. These services include WAP service, mobile phone download service and multimedia messaging service.

At present, China Unicom users who have opened the international roaming service also can use the GPRS roaming service. If they apply to cancel the roaming service, the GPRS roaming service will be cancelled at the same time.

The GPRS international roaming service is charged by flow rate. In Taiwan, the price is CNY0.05 per kilobyte and in Hong Kong, it is CNY0.02 per kilobyte.
